Further, described button include manipulated key, cursor set key, check key, circulation plus key, operation/stop key,
Reset key.
Further, described power module be MCU module, buzzer, driver 5V power supplys are provided, provided for relay
12V power supplys.
Compared with prior art, the LED on off test device of the utility model offer is simple and practical, for surveying
The aging life-span of LED is tried, it is easy to operate, it is economic and practical.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Accompanying drawing 1 is the theory diagram of this test device；
Accompanying drawing 2 is the circuit diagram of this test device.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, a kind of LED on off test device, including MCU module, power module, relay and display
Device, described power module is connected on MCU module, relay, buzzer and driver, and the electricity of different voltages is provided for it
Source, described display is connected in MCU module by driver, and described relay three, which is connected with, installs the defeated of lamp to be tested
Enter output interface, wherein, it is connected with buzzer and button on the MCU.MCU major function is exactly the state for judging button,
The instruction set according to button, inside carries out timing, when reaching the time set, control relay switch motion, and internal meter
Number, presses and can also be controlled when checking key numeral method setting time value and count value.Its button includes manipulated key, cursor and set
Put key, check key, circulation plus key, operation/stop key, reset key.Manipulated key is used for the break-make of manual control relay, and cursor is set
Putting key is used to set cursor state, and setting state is entered after pressing, is often clicked, and the position of charactron, which is dodged, moves forward one, directly
Moved to whole.On checking key, the make-and-break time of setting can be checked after clicking, then clicks display counting value, can be repeatedly
Switching.On circulation plus key, press the numerical value dodged on position the corresponding position of rear logarithmic code pipe and plus 1, in 0-9 circulations.On running/stopping
Only key, presses beginning with the break-make of the control timer set after setting up.Stop key is pressed in operation then out of service,
And show number of times.Cursor sets key and circulation plus key just effective after stopping.As shown in Figure 2,4 Digital sum pipe above charactron
Display logical time or logical number of times, below the group of four figures pipe show time broken or disconnected number of times.In running, on
Lower two charactrons wherein last rotational display.Power module is MCU module, buzzer, driver provide 5V power supplys, is
Relay provides 12V power supplys.When pushing button every time, buzzer can all drip, when in test process, break-make number of times reaches most
Operation stops during big value 9999, and buzzer persistently rings, and alarm counts full, points out operator's subsequent operation.
When specifically used, light fixture to be tested is connected on input/output interface, then by the setting key in button, look into
See that key, circulation plus key, operation/stop key, reset key set test parameter, including power on/off frequency, power on/off number of times, single
Conduction time, power-off time, and test device is run, power supply is MCU, driver, buzzer, relay are powered, and MCU passes through
Corresponding parameter is transferred to display by driver, and is shown by display, while the break-make frequency of MCU control relays
And the time, and then control switching electric time and the frequency of test light fixture.
It is understood that specifically described above with respect to of the present utility model, be merely to illustrate the utility model and not
The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, still can be with
The utility model is modified or equivalent, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
